Norfolk Southern train 11V climbs the mountain around track three at Horseshoe Curve near Altoona, Pennsylvania. The entire train can be seen: Engines 8073 and 9311, 87 cars, and helper units 6333 and 6315, a total length of about 5600 feet. The head end is on the left side of the image (running counter-clockwise), and is much higher in elevation than the rear end's helper units. 11V is a daily manifest freight operating between Enola Yard near Harrisburg and Bellevue, Ohio.
